Subject: [PATCH] Prevent automatic installation of dbconfig-mysql (#2059)

Debian opendmarc package has a dependency on dbconfig-mysql, which it
will pull, together with its dependencies, during image build.

Explicitly listing an alternative dbconfig-no-thanks package prevents
installation of unnecessary packages and reduces the image size.
